Front Panel Lights
The paging software scans each interface card looking for incoming telephone calls from
Trunk cards and outgoing paging from the Station cards. The SELECT and TEST3 light
come on each card as the paging software transacts with a Station or Trunk card. It is
normal to see the Trunk cards blink at a slower rate than the Station cards. It is also normal
that one Station card's SELECT light may appear on solid. In fact, it is blinking at the
same rate but for a longer period giving the illusion of being on solid.
For more details on lights and operation, see the section starting on page 71 for Trunk and
Dual Trunk cards, see the section starting on page 97 for Station cards, see the section
starting on page 151 for CPU/MASTER/MODEM/ASYNC cards, see the section starting
on page 197 for Voice cards, and see the section starting on page 307 for Maintenance.
